Signature Modeling and Analysis Tool (SMAT)
–
User's guide

This contract report presents the tool that was developed for the first implementation phase of 3D infrared signature modelling compatible with the KARMA simulation environment developed on behalf of Defence Research and Development Canada – Valcartier in the framework of Public Works and Government Services Canada contract number W7701-052709/001/QCL “Development and exercise simulation”. The main objective of this tool is to support 3D infrared signatures modelling. This report is presented as a user’s guide of the Signature Modeling and Analysis Tool (SMAT) that manages the infrared property database of a 3D model that is needed in the infrared scene generator. SMAT offers control on the environmental conditions, the sensor characteristics and allows for trade-off studies of the modelling choices. SMAT, with the help of a commercial tool for 3D model edition, associates a temperature and a material to each polygon of a 3D model and is based on the KARMA infrared scene generator that computes an infrared scene as seen by a sensor. Analysis methods are available to help in the modelling process and analysis results can be exported for further analysis or reference. Although this tool is relevant for infrared signature modelling, future improvements shall be considered to better support the process.
